How does it work...Magnets work all because it has a magnetic field and without that field, the magnet wouldn't work there for just a hunk of iron ( Or whatever the magnet is made of ). If you have an electromagnet it works because of an electromagnetic field created when electrified. This is the basics of how magnets work. Planetary fields are a completley diffrent story. Palnetary fields are made from the core of the planet then just stay there.
